Most phones will allow you to add multiple numbers to the same contact: Using the phone’s contacts menu (NOT WhatsApp’s) add the updated number to the contact. Do not remove the previous number. Restart WhatsApp (kill it from memory, then relaunch). WhatsApp syncs with your phone contacts on launch. Enjoy an updated contact with chat history!
